"Are you trying to say that you think if Jane Doe uses KC, for her Word file (let's say a novel, for the ease of discussion) that her final KFX file is jpgs? Pages that are jpgs of text?"

No. If you load Kindle Create with a Word doc, as you've described above, then you will always get a reflowable ebook -- not a KFX ebook. In such a reflowable ebook all text will not be represented as images but will be formatted as html text.

But if you load a PDF into Kindle Create you will get a KFX ebook. This only applies to a KPF file generated from a PDF by Kindle Create or Kindle Text Book Creator. In such a file every text page is a max-page-size jpeg image with no embedded html text.

I also used JP Howell's KFX Input plugin with Calibre. I converted both a KPF file(as KFX) and another KPF file(as a reflowable ebook) to epub format and had a look. This also seems to confirm what I've said above.
